This product is widely used for absorbing heat from halogen and xenon lights for experiments that need to avoid UV or heat from those lightings.

◦Keep away from the heat that is released from NIR and IR range and it cuts off the brightness of the NIR and IR light.
◦It also cuts-off spot light and heat during microscope illumination.
◦Light transmitted through the filter does not darken the high transmitted visible light.

Guide

▶The filter can be broken if it is placed too close to a high brightness lamp with its sudden heat. We recommend to strengthen the glass before this operation. (strengthened glass)
▶We can provide customs specification which are not mentioned on-line or in our catalog, please contact our Sales Division with your request.
▶Please refer to here for Wavelength Characteristic Data (Reference Data, EXCEL file format).

Attention

▶The absorption wavelength range can not be used with high power laser and high energy pulsed laser.
▶There is no coating on both surfaces of the filter and there is a transmission loss of about 10%.

Strengthened glass

Glass can be broken under sudden heat effection. Sudden difference of temperature occurs inside of the glass, it is called thermal expansion and the tensile stress of the inside of the glass occurs. The glass will be broken when the stress is beyond machine strength. However, stress is offset, and glass becomes hard to be broken when there is a compression power in the inside of the glass even if tensile stress is caused by heat to glass.
Using this principle, heat strengthened glass was made out of compression stress forcibly in inside glass at the beginning of the process.
In the polishing process, a strengthened glass must be brought to a familiar softening temperature before to the forcibly cooling process. The inner of the glass is higher in density than the outside of the glass.
